Axial McFee-Parungao lead system vectorcardiograms were obtained in 55 patients with type atrial septal defect, aged 3-24 years, prior to and in average 3 years after surgical repair of the defect. Changes of the QRS loop observed after intervention led to the conclusion that the vectorcardiographic signs of right ventricular dilatation consist of a rightward shift of the posteriorly orientated horizontal plane vectors at 50-70 ms of QRS, decrease of the magnitude of vectors around the 40th ms, no changes in the magnitude and orientation of the initial (10-30 ms) QRS vectors as well abnormal departures of the spatial VCG loop from its preferential plane even in the absence of other signs of right ventricular conduction impairment. The above abnormalities vanished after normalization of hemodynamics.
对55例年龄在3至24岁的房间隔缺损患者，在缺损手术修复前及术后平均3年获取了轴向McFee-Parungao导联系统向量心电图。干预后观察到的QRS环变化得出结论：右心室扩张的向量心电图征象包括：在QRS波50至70毫秒时，向后定向的水平面向量向右移位；在第40毫秒左右向量幅度减小；初始（10至30毫秒）QRS向量的幅度和方向无变化；即使在没有右心室传导障碍其他征象的情况下，空间VCG环也偏离其优势平面。血流动力学正常化后，上述异常消失。
